Description

[Detailed explanation of the idea] The present invention relates to improving a mounting device for a liquid crystal panel.

In recent years, there has been active development of electronic watches that digitally display the time on a liquid crystal panel using micro-sized batteries such as silver oxide batteries.

Such electronic watches are installed by fitting the liquid crystal panel into the fitting hole of the frame, but when obtaining the liquid crystal panel, the material constituting the liquid crystal panel must be cut to a specified size. Therefore, dimensional variations in the manufacturing process of the liquid crystal panel cannot be avoided, and it is difficult to securely fit and attach the liquid crystal panel to the fitting hole of the frame without play.

If the liquid crystal panel shakes inside the fitting hole of the frame, the terminals of the liquid crystal panel and the terminals of the board may become misaligned, or the two terminals may become loose in the interconnector that electrically connects these terminals. The liquid crystal panel must be fitted into the fitting hole of the frame body without any play to avoid problems such as abrasion of the contact surface of each terminal due to relative sliding between the terminal and the terminal. be.

For this purpose, conventionally, as shown in FIG. 1, an elastic metal piece 3 is screwed to the inner wall of the fitting hole 2 of the frame 1, and the elastic metal piece 3 presses the side wall of the liquid crystal panel 4. It is known that the liquid crystal panel 4 is fitted and attached to the fitting hole 2 of the frame 1 without play by pressing opposing side walls against the inner wall of the fitting hole 2 of the frame 1.

In such a conventional structure, when the elastic metal piece 3 is formed separately from the frame body 1, the elastic metal piece 3 must be attached to the inner wall of the fitting hole L2 of the frame body 1 with screws or the like, so the number of parts is reduced. There are many disadvantages, such as poor workability and mass production, and the elastic metal pieces 3 can damage the liquid crystal panel 4 and the terminals provided on its periphery.

The present invention eliminates the above-mentioned conventional drawbacks, and allows the liquid crystal panel to be securely attached to the fitting hole of the frame without any looseness. A mounting device is provided.

Each embodiment of the present invention will be described below with reference to FIGS. 2 to 6.

However, the same parts in the drawings are denoted by the same reference numerals, and redundant explanation thereof will be omitted.

First, a first embodiment of the present invention will be described with reference to FIGS. 2 and 3.

In the figure, reference numeral 10 denotes a frame made of elastic synthetic resin, which has a short-axis cylindrical shape with the entire lower surface open and a rectangular fitting hole 11 provided in the center of the upper surface. The liquid crystal panel 12 is fitted.

Inner walls 11a and I on both sides sandwiching one corner A of the fitting hole 11
A suppressing piece 13 is formed integrally with the frame 10 on each of the lbs.

The pressing piece 13 is constructed by providing a notch 14 in the upper wall of the frame 10 in the shape of a planar abbreviation.

The tip of the pressing piece 13 has an arcuate bulge 15 .

The liquid crystal panel 12 digitally displays the time.
A liquid crystal is sealed between a pair of transparent glasses, and a display segment consisting of a transparent electrode of a predetermined shape is provided on the inner surface of the transparent glass, and the display segment is electrically connected to the segment at both edges in the transverse direction of the transparent glass. It is equipped with a terminal.

The terminals of the liquid crystal panel 12 are connected via the interconnector 15.
It is electrically connected to a terminal 18 arranged on the substrate 17 corresponding to the terminal.

The interconnector 16 is a bar with a rectangular cross section, and is formed in layers in the longitudinal direction of an insulating elastic member 19 and a conductive elastic member 20 at intervals much smaller than the interval between the terminals 18.

The board 17 is inserted into the lower opening of the frame 10 and then inserted into the frame 10.
The terminal 18 is installed at a predetermined position on the top surface of the terminal 18 with screws 21.

Furthermore, electronic components such as a crystal resonator and an LSL battery are attached to the lower surface of the board 17.

Therefore, in order to assemble the disassembled state shown in FIG. 3 as shown in FIG.
The liquid crystal panel 12 is pressed in the direction of the corner A of the fitting hole 11 of the frame 10 while being in contact with the terminals on both sides of the frame 10, and is then fitted into the fitting hole 11.

In this attached state, the elastic force of the pressing piece 13 causes the bulging part 15 at the tip to come into pressure contact with the outer walls 12a and 12b of the liquid crystal panel 12, which are the cut surfaces when manufacturing the liquid crystal panel 12, so that the liquid crystal an outer wall 12c that is a reference plane for the panel 120;
12d is pressed against the inner wall 11c=11d of the fitting hole 11.

Therefore, the liquid crystal panel 12 is reliably fixed without shifting from the initially placed position after fitting into the fitting hole 11, and the terminals of the liquid crystal panel 12, interconnector 16, and substrate 17 are not worn out.

Next, a second embodiment of the present invention will be described with reference to FIGS. 4 and 5.

In this embodiment, pressing pieces 22 are integrally formed on the inner walls 11a and 11b on both sides sandwiching the corner A of the fitting hole 11 of the frame 10, respectively.

That is, each pressing piece 22 is constructed by providing a notch 23 in the upper wall of the frame 10 that has a substantially U-shaped planar shape.

The pressing piece 22 has a fixed lower end and an upper deformable end, as shown in FIG. There is.

However, the other configurations and functions of this embodiment are the same as those of the first embodiment described above.

Next, a third embodiment of the present invention will be described with reference to FIG.

In this embodiment, a pressing piece 25a similar to that of the first embodiment is provided on one circular wall 11a sandwiching the corner A of the fitting hole 11 of the frame 10, and a pressing piece 25a similar to that of the second embodiment is provided on the other side wall 11b. Each of the suppressing pieces 25b is formed integrally with the frame 10.

However, other configurations and functions of this embodiment are the same as those of the first and second embodiments described above.

Note that the liquid crystal panel mounting device of the present invention can be used not only for electronic watches but also for small electronic devices using liquid crystal in the display section, such as electronic desktop calculators.

Of course, the shape and number of the suppressing pieces can be set arbitrarily.

In short, the pressing piece for pressing and fixing the liquid crystal panel in a predetermined position may be formed integrally with the frame made of synthetic resin, and various other changes can be made without departing from the gist of the present invention.

As mentioned above, the liquid crystal panel mounting device of the present invention can securely mount the liquid crystal panel into the fitting hole of the frame without any play, and eliminates the risk of damaging the liquid crystal panel and the terminals provided on its periphery. It is possible to reduce the number of parts and improve workability and mass productivity.
